Subject: btrfs: send: remove redundant assignments to variable ret
X-Git-Tag: v6.14-rc1~207^2~123
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0ad40d730ef30e51d3ec4e3b8c9b6691053354a;p=thirdparty%2Flinux.git

btrfs: send: remove redundant assignments to variable ret

The variable ret is being initialized to zero and also later re-assigned
to zero. In both cases the assignment is redundant since the value is
never read after the assignment and hence they can be removed.
